That is good to know.. some years ago I was using spark plugs instead of 1oz lead for fishing off the rocks on light tackle of course because of the cheaper reason, but one of my friends is "sea biologist" he studied oceanology well he told me that spark plugs have some metals and elements that are 5x worse than lead and he invite me to stop using them, he recomemded me using small cuts of REBAR rods they are pure Fe iron and dont affect the reefs or sea creatures at all.
